Position Description:FlexGen is building the future of sustainable energy infrastructure—where datacenters aren’t just power consumers, but smart, responsive participants in a more resilient grid. As part of our energy storage platform team, you’ll engineer control systems that make datacenters more efficient, reliable, and sustainable. We're looking for a systems-minded engineer to develop real-time control applications that orchestrate power routing, thermal systems, and auxiliary infrastructure within our energy-integrated datacenter platform. This role is about high-performance control on Linux-based systems, where milliseconds matter and uptime is everything. Datacenters are critical infrastructure—and they’re also some of the world’s largest energy users. At FlexGen, we're changing the equation. Our HybridOS platform helps facilities operate more sustainably and intelligently, using energy storage to reduce peak demand, support grid reliability, and conserve natural resources. If you thrive at the intersection of physical systems and software—and want to help shape the datacenter of the future—we want to hear from you.
